In order to save her husband’s life, a wife makes the
unimaginable decision to sleep with another man, who has had a
crush on her. Her fateful choice brings terrible consequences
upon her life… A melodrama that tells a tale about the meaning
of love…

After her parents divorced when Cha So-young (actress Hwang
Soo-jung) was still at the tender young age of 10, she lived a
life similar to that of an orphan and grew up taking care of her
sister. In college, she met her future husband Park Yeon-woo
(actor Kim Young-ho) and they got married before she could finish
her college degree. 10 years pass, and believing that the life of
a loved one is more precious than anything else in the world,
So-young makes the decision to sleep with Kang Ji-seok (actor Kim
Yoo-seok) in return for his help in saving her husband’s life.
Kang Ji-seok is angered that the woman he had a crush on 10 years
ago would still stay faithfully in love with her husband, even
after she had an improper relationship with himself. When
So-young coldly tells Ji-seok that she has no feelings for him
whatsoever and only slept with him to save her husband’s life,
Ji-seok is overwhelmed with mixed emotions of anger and shame.
Seo Yi-hyeon (actress Jung Ae-yeon) considered So-young to be a
step below her in the social ladder but when she overhears her
fiance Ji-seok proposing to her, she is shocked and becomes
overcome with jealousy. In a fit of anger, she decides to tell
So-young’s husband of his wife’s infidelity. A rumor about
So-youngs extramarital affair spreads among the neighbors
and out of revenge, Park Yeon-woo has an affair, too. So-young is
devastated at how her marriage is falling apart. Her husband
tells her that she should have let him die instead of dishonoring
him. Steadfastly believing that she would have made the same
decision to sleep with Kang Ji-seok even if she could do it over
again, she ends up moving out of the family home…
